If a random search for dog licenses rolled into my neighborhood, you can bet that I would tell them to come back with a warrant or to get off my property. That is ridiculous. Maybe somebody should send them a copy of the fourth amendment

Once the "officer" notes the existence of the Dog they can legally begin proceeding down the path of ticketing...

I know a lot of people yap about Cat licensing, Horses, Rats, etc. - the greater point, and liability insurance agents can attest to this, is that Dogs are involved in more personal injury/attacks than any other domesticated pet combined. While a large part of it these days is revenue generation, the latter fact, combined with a requirement for shots to be up to date were originally a public safety/health issue for folks to avoid having to get rabies shots after getting nipped trying to deliver the mail, milk, bread, porn or girl scout cookies...
